However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. However, it does have application as a discriminator in determining variations in adherend surface preparation aztm and adhesive environmental durability. Current edition approved Oct.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. It is r897 to grind all metal specimens at the same time. Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. We are confident that we have what you are looking for.
ASTM D – 08() Standard Test Method for Tensile Properties of Adhesive Bonds
Start test loading of the specimen as quickly as possible. The ASTM 8d97 takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. ASTM D is primarily comparative.
A range may be prescribed for any variable by the manufacturer of the adhesive if it can be assumed by the test operator that any arbitrarily chosen value within such a range or any combination of such values for several variables will be acceptable to both the manufacturer and the purchaser of the adhesive. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Use the self-aligning type. That is, if the cement has adhered to the metal test pieces and no voids are visual, it represents a percent cohesive failure. ASTM D e1. Contact failure refers to lack of glue lines being in contact due to uneven surfaces, poor pressure distribution, etc. Adhesion failure refers to the lack of adhering to metals being fastened. This will be based on a visual inspection.
